A doll is provided having a hollow body with one or more pivotally mounted limbs arranged for movement from a normally retracted position at the side or in front of the body to an actuated position at a higher location or across the body by operating a manual actuator such as a depressible member which is accessible to the rear of the body. In another embodiment, a mechanism subassembly is constructed for selectively operating an arm and leg of a doll. The arm or leg of the doll is frictionally ...

This invention relates to a method and apparatus for displaying the presence or absence of signal activity. Signal activity is stored at a slow rate optimum for the receiver and then read out at a fast rate (above that of the flicker rate), so that the operator has a visually constant display output and fast phosphors can be used with high light outputs. The display is in the form of a "falling raster" in which successive stored sweeps are vertically ordered; the newest at the top, the oldest at...

This invention provides 2-phenyl-2-hydroxy-cyclohexane-carboxylic acid and 2-cyclohexyl-2-hydroxy-cyclohexane-carboxylic acid as highly effective choleretic agents. The administration of effective dosages of these compounds by various routes results in marked choleresis.

An activity toy with which a child may create needle craft like textured designs using plastic or amorphous solid substances. In order to simulate the strands or nubs that create the textured design in neddle crafts a stand supported on a surface holds a screen having mesh spaces extending between the opposed sides of the screen. The stands hold the screen spaced from the surface with one side of the screen facing the child. An extruder for the plastic substance is positioned adjacent the side o...

An activity center includes a plurality of polygonal frames pivotally connected together. Each frame includes an open area accessible from each side thereof and an activity device mounted therein whereby each device is accessible from either side of its respective frame. At least some of the activity devices are movable with respect to their respective frames. Particular elements of the activity center are interchangeable among the respective activity devices and the devices are generally cooper...

An activity kit for drawing, painting, sewing or the like, comprising a rigid case providing a flat activity surface and a cavity within the case for receiving a roll of medium, such as paper on which the activity is to be carried out. Medium from the roll is fed between medium guide positioned on the activity surface adjacent in the direction of dispensing of the medium. A medium dispensing control may be provided to restrict the medium which can be pulled at one time to only so much as would c...

A sheet of plastic material folded at the middle and forming a pair of side panels, with the juncture edge between the panels lowermost and the panels extending upwardly therefrom, forming a tote. The ends and top are open, and the panels can be opened to a flat position. Plastic pocket pieces are secured to the panels, forming large pockets between themselves and the panels, and certain of those pocket pieces have additional pocket pieces secured thereto to form additional and smaller pockets. ...

A process for assaying the quantity of angiotensin and renin employing radioimmunoassay techniques, comprising the steps of combining solutions of (1) antibody to angiotensin coupled to poly-L-lysine, (2) angiotensin labeled with radioactivity, and (3) varying known amounts of unlabeled angiotensin to produce mixtures having a pH of about 7.0 to 9.5, which upon incubation form angiotensin-antibody complexes. The mixtures of angiotensin-antibody complexes (antibody-bound angiotensin) and free ang...

A cardiovascular monitoring system employs a photoelectric monitoring circuit to obtain analog signals corresponding to the heartbeat of a subject. Cooperating amplification and detecting circuitry provide an audible tone corresponding to each pulse beat as well as a readout of the pulse rate of the subject and blood pressure. Circuitry is provided which detects and displays both systolic and diastolic blood pressure. Additionally, an auxiliary input permits selection of the subject's pulse at s...
